5. Spindle
The spindle driver circuit consists of 3 section: Torque sense amp, Current sense amp, and Power driver.
Torque sense amp compares and amplifies E
C
and E
CR
signals from SERVO, and sends them to current sense amp. With
voltage comparison, it determines the signal as forward or reverse.
Current sense amp limits the current in Motor(Io) by comparing output current signal from torque sense amp with the
current of R
CS
.
Power driver output the current to the motor based on the current generated form current sense amp.
